This is pretty much the same as the apocryphal story about Dustin Hoffman in Marathon Man living on the street for 3 days to prepare for his role and Laurence Olivier saying wouldn't it be easier to just act.

Does this post attack Obama's Presidential acting skill? So what he reads his words off teleprompters? It is a hard enough job to act like an American President when you are carefully working to make a ruin out of the place. Memorising his script should be optional. Don't you want him to succeed?
